Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an assembly of an air guide part for a structural part of a vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly of an air guide portion for a structural component of an automobile and a corresponding automobile.

The function of this type of air guide is to allow the front apron skin of the motor vehicle or the front apron skin of the motor vehicle to guide air to a series of combined components, also referred to as so-called "cooling cases" And channeling the air entering through at least one vent opening or grill. The term cooling case is used to refer to a series of parts, often necessary for cooling the engine, that are laminated or partially overlaid to form a layer. The cooling case typically has a water radiator for engine cooling, and may also include an air / air exchanger (charge air cooler [ Refroidisseur Air Suralimentation - RAS ]) and a condenser.

The term " functional front end "( FAT ) refers to a structure located in front of an engine block, the function of which is to support various elements, mainly the radiator of the engine block. The functional front end can take many forms. In some cases, it may be a single cross-member. In other cases, the function front end can be a chassis of a somewhat more complex design type including the cooling case. The front end of the function may include various roles such as a hood stop support, a hood lock support, a leg supporting the hood lock, and the like.

The air guide is typically fastened to the structural part of the function front end by fastening means. The fastening means comprises a receiving part extending in the transverse direction of the motor vehicle and integral with the function front end, and a motor which extends in the longitudinal direction of the motor vehicle and is received in a hole in the receiving part, And a clipping finger. Since the receiving portion is extended to some extent in the transverse direction with respect to the automobile, when the clipping finger is broken due to a small front impact generated, the air guide abuts against the receiving portion and stops, So that the ends are seated in the supporting units, particularly the radiator. Therefore, when the air guide moves backward toward the rear of the automobile following the front impact, the unit or units supported by the functional front end are liable to be damaged due to such support even during a small front shock. In this case, it may be necessary to replace the units, which increases the cost of repair. The air guide portion often includes deformable portions that can be restrained from damage to the units supported by the functional front end by absorbing a portion of the impact. However, in the regions of the fastening means of the air guide to the function front end, they can not be deformed due to their fastening function, thus forming hard points for supporting the air guide to the function front end .

Therefore, there is a need for a means for fastening the air guide to the stationary part, so that damage to the parts supported by the stationary part of the vehicle in the event of an impact on the front end of the vehicle can be suppressed.

The present invention provided for this purpose is an assembly of an air guide for a structural part of an automobile, the assembly comprising at least two fastening means for fastening the air guide to the structural part, Wherein each of the fastening means includes a first fastening component integral with the air guide and a second fastening component integral with the structural component, wherein the first fastening component and the second fastening component are integrally formed with the air guide, The fastening parts are formed to cooperate together in the same fastening direction, and have the following features.

The fastening means project laterally from a frame formed by the lateral edges of the structural part in a direction substantially perpendicular to the direction of fastening.

The first fastener is coupled to the air guide by means of a retaining means configured to break following the impact in a direction substantially parallel to the fastening direction.

The side edges of said air guide have guiding portions located substantially opposite sides of said second fastening components and each guiding portion comprises a first fastening component, 2 fastener is guided to the inside of the air guide portion by the side edge of the structural component supporting the fastener component and the air guide portion moves toward the structural component in a direction substantially parallel to the fastening direction due to the breakage .

According to this type of configuration, in the case of a small frontal impact, the air guide can be moved relative to the structural part, so that the air guide can be prevented from coming into contact with the structural part, especially with the fastener of the structural part, Thereby reducing the risk of damage to the units supported by the unit.

The breakage of the holding means can be accomplished, for example, by a film hinge or by a resolvable and / or detachable link, such as a hinge, a thickness reduction zone, a slot, a notch, etc., .

The guide portion may be formed to guide the second fastening part to the inside of the air guide portion in particular.

The guide portions may form sidewalls of the air guide or be part of the sidewalls thereof. The free edges of the side walls of the air guide define lateral edges of the air guide.

Advantageously, but not exclusively, the avoidance of the structural part can be achieved by the free edge of the guide part towards the structural part, which is not the opposite of the structural part in the fastening direction. In other words, the free edge of the air guide portion, which can form part of the side edge of the air guide portion, is not reversed with respect to the side edge of the structural component.

Advantageously, but not exclusively, the guiding portion may form a concavity open towards the inside of the air guide and the structural component, the recess being substantially parallel to the direction of engagement And has a splayed shape from the air guide portion toward the structural component. Thereby, while the air guide moves toward the structural component, the lateral edge of the structural component is guided by the surfaces of the recess. The widened configuration allows the lateral edges of the structural component, especially the second fastener, to enter the recesses during the movement. The recesses may comprise one or more, for example three, planar surfaces.

Specifically, the guide portion can form a concave portion having a shape that is opened only at a portion of its inner surface. For example, the guide portion may have at least one tapered section, for example a single tapered section, widened towards the structural component in a direction substantially parallel to the direction of the fastening. This inclined section can be a particularly planar surface. The free end of the inclined section may be configured to be further inclined toward the outside of the air guide portion, whereby the end portion of the concave portion can be further opened. The surface of which can be inclined with respect to the side wall of the air guide portion in which the guide portion forms a part.

Generally, the dimension of the recessed shape of the raised shape can be selected in accordance with the dimension of the second fastening component, so that the second fastening component can be selected to be guided inwardly of the recessed portion.

Advantageously, but not exclusively, the retaining means can couple the first fastener to the guide portion. This makes it possible to guide the second part into the guide part, whereby the guide part comes very close to the second guide part.

Advantageously, the first fastener may be located at least partially inside the guiding portion, which may facilitate guiding of the second part inwardly thereof.

For example, the retaining means can link the first fastener to the free edge of the guiding portion, which enables the implementation of the retaining means.

In particular, the free edge of the guiding portion may be the free edge of the recessed shape of the widened shape described above, in particular the free edge of the inclined section. This makes it possible to adjust the breakage force of the holding means in accordance with the inclination of the opened shape.

Finally, the first fastener may be configured to at least partially close the opening of the recess facing the structural component when it is integral with the guiding portion.

Advantageously, but not exclusively, the retaining means may comprise a hinge connecting the first fastener to the free edge of the guide portion.

Specifically, the hinge may be a film hinge, a thin hinge, or a pre-slit with or without a notch. In other words, the holding means may be integrally formed with the first fastener made of a polymer material and the air guide. This type of hinge enables the air guide to be manufactured by casting, in which the first fastener is cast at a location called the casting position and then rotated to the use position. The casting position may be, for example, 90 ° to the use position.

Advantageously, but not exclusively, the retaining means may comprise at least one retaining part, the retaining part being in particular of a first position in which the first fastener can cooperate with the second fastener, 1 fastening parts. Depending on the position of the first fastener, the retaining part or the retaining parts can be inside or outside the air guide, in particular the guide part.

The holding part comprises:

A stop formed by the boss on the guide portion;

A mounting stopper fastened to the guide portion;

A fastening lug integral with the first fastening part and the guide part; And

A fastening lug integral with said first fastener, said fastening lug having an end that contacts or is inserted into said hole in said guide portion; ≪ / RTI >

The various stoppers and fastening lugs as described above are particularly suitable for:

- to prevent the first fastening component from moving toward the inside of the air guide in a direction substantially parallel to the fastening direction;

- to allow for damage-induced movement during a frontal impact of a predetermined force, for example; .

To this end, the number, position, dimensions, and / or the fastening method of the stoppers may be selected accordingly. The stopper may protrude, for example, inwardly of the guide portion in a direction substantially perpendicular to the fastening direction. The number of the stop portions may be two or more, but is not limited thereto.

Similarly, the number, location, dimensions, and shape of the locking lugs can be determined according to the desired point of failure. The number of locking lugs may be two or more, but is not limited thereto.

For example, the fastener lugs integral with the first fastener and the guiding portion can couple adjacent outer surfaces of the first fastener and guide portion.

According to another example, a fastening lug having one end inserted into the hole in the guide portion or in contact with the hole and integral with the first fastener is provided, for example, on the inner side of the air guide, And may extend substantially parallel to the fastening direction. The hole may be a through hole. The end inserted into the hole or in contact with the hole may be formed to allow the locking lug to be removed out of the hole. To this end, this end may have a rounded shape.

Wherein the retaining part is a locking lug which is integral with the first fastening part with one end inserted into or in contact with the hole in the guiding part, May include inclined surfaces formed to move the locking lugs away from the holes in the guiding portion, especially while moving in a direction substantially parallel to the locking direction, causing the ends of the locking lugs to deviate from the hole There is sufficient spacing. This type of inclined surfaces therefore allows for easy removal of the fastening lugs. These inclined sections may be integral with the inner surface of the guiding portion.

The various maintenance means described above may or may not be combined with one another. In particular, hinge-like holding means may be combined with one or more stop-type or locking-lug-type retaining parts, only a plurality of retaining parts may be used, or any other combination may be used.

The first fastening part and the second fastening part of the fastening means can be selected from a fastening clip and a receiving part, the fastening clip being formed to engage with a lock mechanism in the receiving part in the fastening direction. For example, the first fastener may be a fastening clip. However, the present invention is not limited to this embodiment. Specifically, the first fastener and the second fastener may be plates drilled to receive rivets, screws, or the like.

Since the present invention is not limited by the number and position of fastening means, it is also possible to use more than one fastening means, which may or may not be distributed over more than two lateral edges of the structural part and air guide.

The invention also relates to an air guide intended to be assembled to the structural parts of an automobile as described above.

This type of air guide comprises at least two first fasteners disposed at lateral edges and the first fasteners are configured to cooperate with second fasteners integral with the structural part in the same fastening direction And has the following characteristics.

The first fastener is laterally projected from the frame defined by the lateral edges of the structural part in a direction substantially perpendicular to the direction of engagement when the air guide part is assembled to the structural part.

The first fastening part is coupled to the air guide by holding means formed to break following the impact in a direction substantially parallel to the fastening direction.

The lateral edges of the air guide have guide portions located on substantially opposite sides of the second fastener when the air guide is assembled to the structural component, each guide portion having a first fastener component cooperating with the second fastener component, Is formed to guide the side edge of the structural component supporting the second fastening component to the inside of the air guide portion after the breakage of the air guide portion from the movement of the air guide portion toward the structural component in a direction substantially parallel to the fastening direction Lt; / RTI >

The guide portions, the retaining means, and the first fasteners may be as described above.

The present invention also relates to an automobile including the air guide portion according to the present invention.

Figures 1 and 2 show, in part, an assembly of air guides 10 for structural parts 20 of a motor vehicle. The structural component 20 has lateral edges 21 defining a frame. Although only the vertical side edges 21 are shown in Figs. 1 and 2, the frame has a substantially rectangular shape as a whole. However, the present invention is not limited to such a specific shape. The structural component 20 forms part of the functional front end of the vehicle and supports the radiator 1. [

The air guide 10 shown fully in Fig. 3 has a front face 10a (see Figs. 1 and 2) directed towards the front of the vehicle and a rear face 10b seen in Fig. The air guide portion 10 is assembled to the structural component 20 on the rear surface 10b side. The air guide 10 in this case has a substantially rectangular shape defined by the side walls 11 and 12 (two substantially vertical side walls 11 and two substantially horizontal side walls 12) do. The air guide 10 forms two guide channels 13. The present invention is not limited by the shape of the air guide and / or the number of guide channels. The guide channels 13 are intended to deliver air from a ventilation opening at the front end of the vehicle (not shown) to the radiator 1 supported by the structural component 20. [

On the rear face 10b side, the air guide 10 has side edges 14, 15 corresponding to the free edges of the side walls 11, 12, respectively.

The air guide portion 10 is assembled to the structural component 20 by a plurality of fastening means 30 arranged at the lateral edges of the structural component and the air guide portion. In this example, the fastening means is arranged at the vertical side edges 14,21. However, they may be located at horizontal lateral edges, or at horizontal lateral edges and vertical lateral edges.

Each of the fastening means 30 is formed so as to cooperate together in the same fastening direction (in the longitudinal direction X of the automobile in this example) and the first fastening members 31 integrally formed with the air guide portion 10, And a second fastening part (32) integral with the first fastening part (20). The fastening means 30 is further projected in a direction substantially perpendicular to the fastening direction from the frame defined by the lateral edges 21 of the structural component 20, that is to say laterally substantially in the YZ plane.

The first fastening part 31 is joined to the air guide part 10 by the holding part 40 and the holding part 40 is formed so as to break after the impact in the direction substantially parallel to the fastening direction . Thus, the first fastener 31 can be in two positions:

- In order to ensure the assembly of the air guide portion 10 with respect to the structural component 20 as the use position (Fig. 1) associated with the air guide portion 10 by the holding means 40, (32).

- a free position (Fig. 2) which is no longer connected to the air guide following the breakage of the holding means 40;

Finally, the air guide 10 has guiding portions 50 at its lateral edges 14, which guide portions 50, in particular in the fastening direction, are located substantially on the opposite side of the second fasteners 32 Located. Specifically, the guiding portions 50 are located at the lateral edges 14 supporting the first fasteners 31.

Each guiding portion 50 has a breakage caused by the movement of the air guiding portion 10 toward the structural component 20 in a direction substantially parallel to the engaging direction as shown in Fig. 2, that is, In the case where the holding means 40 for connecting the fastening part 31 to the air guide part 10 is damaged, the side edge of the structural part 20 supporting the second fastening part 32 21) inside the air guide portion (10).

In the example shown in the figures, the guiding portions define an interior of the air guide and a recess open toward the structural component, the shape extending from the air guide to the structural component in a direction substantially parallel to the fastening direction . This shape similar to the gulley or funnel allows the second fastening part 32 corresponding to the breakage of the holding means 40 of the first fastening part 31 to be guided inward of the guiding part . In particular, the edges of these recesses are not located on opposite sides of the structural part in a direction substantially parallel to the direction of engagement, thereby facilitating the introduction of the second guide part into the guide part, As shown in Fig.

Exemplary embodiments of the retaining means and guide portions will be described with reference to Figs. 4-7. In the exemplary embodiments shown in FIGS. 1 to 7, the same parts have the same reference numerals, and are denoted by quotation marks ('), double quotation marks (' '), and triple quotation marks (' '') Are added.

4A shows a guiding portion 50 'in the form of a flared recess. The guiding portion 50 'has a sloping section 501' (FIG. 4B) that extends in the direction of the structural component in a direction substantially parallel to the direction of engagement. The inclined section 501 'extends substantially as an extension of the side wall 11 of the air guide. The remainder of the recess is formed by two other side surfaces 502 'which are substantially perpendicular to the side wall 11. These different surfaces 501 ', 502 ' are in substantially planar form and are joined by a rounded shape.

In this embodiment, the retaining means 40 'connects the first fastener 31' to the guiding portion 50 ', which retains the guide 40', as shown in Figures 4a and 4b, Permits the rotation of the first fastener 31 'relative to the free edge 503' of the portion 50 ', which is directed toward the structural component 20. 4A and 4B show the first fastener 31 'in the use position and the third position, in the third position it is in the non-use position, but in connection with the guide part.

In this case, the first fastener 31 'has a support plate 310' that supports a fastening clip 311 '. In this case, the holding means 40 'links the support plate 310' to the guide portion 50 '.

In this case, the retaining means 40 'comprises a hinge 401' and two retaining parts 402 ', the hinge 401' having a free edge 503 'at the same height as the inclined section 501' Extends between the support plates 310 'and each of the support parts 402' interconnects the free edge 503 'and the support plate 310' at the same height as the side section 502 ' 4c). In this example, the hinge 401 'may be a film hinge, and each retaining part 402' is a fastening lug, in which case the fastening lug is substantially in the form of a set square One part of which is integral with the support plate 310 'and the other part is integral with the outer side of the side section 502' of the guide part 50 'at the use position of the first fastener 31' . The retaining parts 402 'and the hinge 401' may be fusible, which may be obtained, for example, by making a thin portion of the material, or a slot, notch, separable shape.

The first fastener 31 ' may therefore be provided in the direction of the structural component 20, for example after being cast with the air guide in a casting position located at 90 [deg.] From the use position, 'To a substantially closed use position. The retaining parts 402 'may then be coupled to the air guide.

In a variation not shown, the first fastener 31 'can be simply held in the air guide by the retaining parts 402', in which case it is produced separately from the air guide, Or the like.

As can be seen in this embodiment, the first fastener 31 'closes the open end of the guiding portion 50' towards the structural component, i. E., In the fastening direction of the fastening means. Specifically, the first fastener 31 'closes the open end of the guiding portion 50' along the free edges of the guiding portion 50 '.

5A to 5C show another embodiment which is different from the previous embodiment in terms of the shape of the guiding portion 50 " and the holding means 40 ". As in the previous example, the first fastener 31 '' has a support plate 310 '' for supporting the fastening clip 311 '' and the retaining means 40 ' 'To the guide portion 50' ', but to the inner side.

This embodiment differs from the previous embodiment in the following points:

- the lateral sections 502 '', which are substantially orthogonal to the side wall 11, are associated with a central, inclined section 501 '', which flares towards the structural part in a direction substantially parallel to the direction of the fastening, (Figs. 5A and 5B).

- the retaining means 40 '' comprises two retaining parts 402 '' in the form of a stop arranged on the side sections 502 '', Away from the free edges of the side sections 502 ".

- the retaining means 40 " includes a hinge 401 " extending between the free edge 503 " of the guiding portion 50 " at the same height as the sloping section 501 " ''), And the free edge 503 '' is positioned on the end portion 504 '' of the tapered section 501 '' and is further inclined toward the outside of the air guide.

Thus, the support plate 310 " extends a little below the free edges of the side sections 502 ", whereby the guide portion 50 " And the second fastener cooperating with the first fastener 31 '' can not unintentionally come out of the guide portion 50 ''.

Each stop 402 " has an end surface in contact with the support plate 310 ", which has a rounded shape so that the support plate 310 " Allowing rotation of the support plate 310 " after rotation, and then the hinge 401 " is broken. The breakage of such a hinge 401 " can be facilitated by the presence of the triangular supports 312 " or cams such that the triangular supports 312 " or cams are directed towards the inside of the guide portion Is integral with the face of the support plate 310 " and is supported on a more inclined end 504 " of the section 501 " (Fig. 5C).

The stops 402 " may be mounting stops or may be formed by a boss on the wall of the guide portion.

The embodiment shown in Figs. 6A and 6B is substantially different from the previous embodiment in terms of the shape of the retaining parts 402 '' '. In this case, the first fastening component 31 '' 'has a support plate 310' '' for supporting the fastening clip 311 '' ', and the retaining means 40' '' ') To the guiding portion 50' '', likewise partially inboard thereof. To this end, the hinge 401 '' 'is positioned between the free edge 503' '' of the guide portion 50 '' 'and the support plate 310' '' at the same height as the tilted section 501 ' And this free edge 503 '' 'is located on the end portion 504' '' of the tapered section 501 '' 'and is further inclined toward the outside of the air guide.

The retaining means 40 '' 'comprise two retaining members 402' '' in the form of locking lugs and one end of the retaining members 402 '' ' , And the other end 403 '' 'of the retaining members 402' '' is integral with the side of the inwardly facing support plate 310 '' ' Through hole 505 " 'provided. It can be seen that the shape of the end portion 403 " 'is round, which means that after the first fastening component 31' '' is rotated toward the inside of the guide portion, the fastening tabs 402 ' (505 " ').

The embodiment shown in Figs. 7A and 7B is similar to the previous embodiment, wherein the intrinsic difference between the two is at the position of the receiving lugs of the retaining lugs. This embodiment of the guide portion 50 and the holding means 40 corresponds to that shown in Figs. In this case, the first fastener 31 has a support plate 310 for supporting the fastening clip 311, and the retaining means 40 links the support plate 310 to the guide portion 50 , Likewise partly on its inside. To this end, a hinge 401 extends between the free edge 503 of the guiding portion 50 and the support plate 310 at the same height as the central inclined section 501, Is positioned on the end portion 504 of the sloping section 501 which is more inclined toward the outside of the part.

The retaining means 40 includes two retaining parts 402 in the form of locking lugs, one end of which is fixed to the side of the supporting plate 310 facing the inside of the guiding part 50 And the other end portion 403 of the retaining parts 402 penetrates the hole 505 provided on the inclined section 501 at the center of the guide portion. In the illustrated example, as can be seen in FIG. 7A, the protruding portion 404 penetrates the hole 505. This protruding portion 404 has a triangular shape, and the angle of the protruding point becomes staggered, allowing the locking lug to separate from the hole 505.

In this embodiment, the disengagement of the locking lugs 402 from the holes 505 is facilitated by the inclined surfaces 506 located on the inner surfaces of the side surfaces 502. One of these sloping sections 506 is also shown in Figure 2 wherein the sloping sections 506 are configured such that the first fastener 31 rotates towards the inside of the guide portion and the fastener lugs Lt; RTI ID = 0.0 > 402 < / RTI > And therefore their inclination is determined so that sufficient divergence occurs to cause the end of the locking lug 402 to fall out of the hole 505. [ In other words, during the rotational movement, the locking lugs 402 are separated from the holes 505 by being pulled toward each other.

Similarly, in the embodiments described with reference to Figs. 6A, 6B, 6C and 7A, 7B, the hinges 401 '", 401 To facilitate breakage, the first fasteners 31 '' ', 31 are seated on the more sloping ends 504' '', 504 of the sections 501 '' ' 310 of the support plates 310 '' ', 310 facing the inside of the support plates 310' '', 310.

In the embodiments described with reference to the drawings, the first retaining part is a fastening clip, but it may be a receiving part of the fastening clip, for example a drilled plate formed to cooperate with a fastening clip, And can be fastened and held in the same manner as the support plate described above. Alternatively, drilled or complete plates may be used for riveting or screw assembly.
